------------------------------------------

That would be good to do. However, how do you decide whether it is the first time we see an element in the window or whether we have seen the window before?

> I find that we call ctx.registerEventTimeTimer(window.maxTimestamp()) every time when an element is received in the window. Even though it doesn't affect the result because it uses a Set, but I think it can still be an improvement if we call it only once.
